Abstract: Methods, systems, and devices for wireless communication are described. A first network node may transmit, to a second network node, first information that is indicative of a bandwidth capability of the first network node and a first random access message. The second network node may transmit a second random access message in response to the first random access message and via a quantity of physical resource blocks (PRBs). The second random access message may indicate a time period for transmission, by the first network node, of a third random access message responsive to the second random access message. The time period may be based on a threshold time period associated with the bandwidth capability of the first network node, and the threshold time period may be based on the quantity of PRBs via which the second random access message is transmitted.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may establish a sidelink communications link with a second wireless device. The first wireless device may transmit, to the second wireless device, an indication of a capability to support a configuration for phase continuity between multiple physical channel transmissions of the sidelink communication link. The first wireless device may transmit one or more physical channel transmissions, which each may be associated with a set of one or more demodulation reference signals (DMRSs) to the second wireless device in accordance with the indicated configuration for phase continuity between the physical channel transmissions. The second wireless device may determine channel parameters associated with the one or more physical channel transmissions based on a joint channel estimation associated with the one or more sets of DMRSs.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to be in agreement on spatial quasi co-location (QCL) assumptions for transmission in certain scenarios. The techniques may be used, for example, to determine QCL assumptions for downlink transmissions sent in an initial control resource set (CORESET) on an initial downlink bandwidth part (BWP) where dedicated signaling of such assumptions may be lacking. In some cases, the techniques may involve a UE determining a beam to use for monitoring for a physical downlink control channel (PDCCH) transmission on the initial CORESET in the initial downlink BWP that lacks dedicated signaling of QCL information and monitoring for the PDCCH on the initial CORESET in the initial BWP using the determined beam. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless device may modify a cyclic redundancy check (CRC) generation and attachment operation based on a secret key to support enhanced security. In some examples, a first device may identify a set of data to transmit to a second device and prior to transmitting the set of data, the first device and the second device may obtain a set of key bits for data protection. The first device may generate a bit vector based on a subset of the set of key bits and a cyclic redundancy check polynomial. The transmitting device may then generate an encoded codeword based on the bit vector and transmit the encoded codeword to the second wireless device. The second device may decode the encoded codeword and obtain the set of data based on the set of key bits.

Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for determining, such as by a user equipment (UE), a bundle size for demodulation reference signal (DMRS) bundling for an uplink random access channel (RACH) message sent with repetition and transmitting the uplink RACH message with DMRS bundling according to the determined bundle size. For example, in some aspects of the present disclosure, the uplink RACH message is sent with a number of repetitions and the bundle size is determined as a function of the number of repetitions. In some aspects, the bundle size is determined based on operation band. In some aspects, the bundle size is determined, based on a duplexing mode in which the UE is operating. In some aspects, the bundle size is determined, at least in part, based on signaling from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A communications device such as a user equipment (UE) may receive a control message that indicates at least one transmission configuration to apply for bandwidth part (BWP) switching between multiple BWPs, to apply for component carrier (CC) switching between multiple CCs, or both. The at least one transmission configuration may be associated with a plurality of scheduled transmissions (such as semi-persistent scheduling (SPS) or configured grant (CG) transmissions) associated with a BWP or CC configuration. The UE may then receive a switch command to switch from a first BWP to a second BWP, from a first CC to a second CC, or both. The UE may then transmit one or more scheduled transmissions in accordance with the at least one transmission configuration.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability associated with maintaining phase continuity and power consistency for demodulation reference signal (DMRS) bundling between a full-duplex slot and a half-duplex slot. The UE may transmit a first signal during a first slot of a first time domain window (TDW) associated with the DMRS bundling. The UE may determine whether to terminate the first TDW based on the capability associated with maintaining the phase continuity and the power consistency between the full-duplex slot and the half-duplex slot. The UE may transmit a second signal during a second slot of the first TDW or a second TDW based on the determination of whether to terminate the first TDW.
